I managed to make it work by hacking CustomParamsRequest and rebuilding
freemarker.jar. I'm using this for now and i hope it's good enough until i
manage to complete the transition from JSP to ftl.
page3.jsp, right? (When you try that, just print them, because
getParameterNames might have its own problems.) Then in page2.jsp, the
jsp:include didn't add "param2" to the request. That's the jsp:include
implementation's doing, and I don't see why it's happening. What's the
class of the request object in page2.jsp and in page3.jsp?
Best regards,

I'm working on a project for replacing an existing JSP code base
with Freemarker. I'm trying to do it progressively, that is I still
want to be able to include some JSP files from my new Freemarker
templates.with Freemarker. I'm trying to do it progressively, that is I still

The JSP pages that I include directly from .ftl files work fine,
but there is a problem when a JSP page included from an ftl tries to
include another JSP page and pass it some parameters. The second JSP
file loads but doesn't receive the parameters from the calling JSP,
it only gets the parameters that the .ftl passed to the first JSP.

params={"param1": "param1"}/>but there is a problem when a JSP page included from an ftl tries to

request.getParameterNames() only contains param1 for both page2.jsp

Just to be sure, you are seeing "param1" only, in both page2.jsp andpage2.jsp

Is there a way for this to work? If so, what am i doing wrong?
